I'd like to get to know the world of ferrite and magnetics a bit more, mostly because of the lack of understanding of the properties of magnetic materials used in transformer cores. Specifically ferrite. I plan to dedicate my old analog scope into a bh curve plotter and saturation tester. I've gained a lot from this  page, and I'd like to build a more permanent and universal testing platform based off of the fundamental circuit shown.
My main question is does the injected primary signal have to be sine, or can it be square? with a square wave wouldn't the legs of the curves just be traced a lot faster on the scope, as opposed to a more uniform rate of plotting for a sine? Or does the fast transitions of the square wave alter the measurement?
Thanks
ps- on a side note, does anyone know where I might find a flyback transformer core of much larger dimensions? one that can handle a few .25" copper pipe turns around it? and has a very large Ae...

Inverter Microwave oven ferrite cores are good to 1kW
sinewaves are used to get freq vs core parameters hard to do with a squarewave that is made up of odd harmonics out to infinity (this includes the fundamental)
